What You'll Learn
Prepare the surface and protect surrounding areas
Preparing the surface and protecting the surrounding areas are crucial steps when spray painting interior plastic doors to ensure a professional finish. Here are the detailed steps to follow:
Firstly, decide on a suitable work area. Choose a well-ventilated space, preferably an open area, to ensure proper airflow during the painting process. If you are painting the doors inside your home, select a room with good ventilation and cover any furniture or items in the vicinity to protect them from paint spray. Alternatively, you can set up your work area outdoors, ensuring it is protected from any wind that might carry the paint.
Next, prepare the surface of the door itself. Remove all hardware, including hinges, latches, handles, and levers. Carefully place each piece of hardware in a small plastic bag and label it for easy reassembly later. Use masking tape or painter's tape to cover any areas you do not want to paint, such as the edges of the door or any glass panels. If your door is leaning against a wall, you might want to hang plastic to protect the surrounding area from paint spray.
Now, it's time to prepare the paint sprayer. Practice using the sprayer before starting on your doors. Set up some old boxes or a piece of plywood and practice spraying to get a feel for the spray pattern and velocity. This will help you achieve a smoother and more consistent finish when you start painting the doors. Ensure the paint sprayer nozzle is clean and free of any dried paint, as this can cause clogging and result in an uneven finish.
Finally, prepare the doors for painting. Whether you are painting the doors horizontally or vertically, ensure they are securely propped up and will not fall. One method is to use plastic braces or door deckers, which screw into the hinges and hold the doors in place. Alternatively, you can use short sticks of wood or door stop material cut into sticks, placed between the door and the wall at the top edge to achieve the right lean.

Choose the right paint sprayer
When choosing the right paint sprayer, it is important to consider the size and nature of your project. Paint sprayers come in a variety of types, power levels, adjustability, price ranges, and intended uses.
For small to medium-sized projects, HVLP (High Volume, Low Pressure) sprayers are a good option. They atomize materials into fine particles, providing a smooth and professional-quality finish. HVLP sprayers are ideal for spraying decks, furniture, cabinets, sheds, or interior walls. They are also suitable if you are looking for a flat finish, although they may not work as well with latex paint. The Wagner FLEXiO line of products is a good option for HVLP sprayers, with prices ranging from $100 to $350.
For larger projects, High Efficiency Airless Sprayers are a better choice as they can cover large areas quickly with unthinned paint or stain. They are ideal for tackling projects with speed and efficiency, offering 55% less overspray compared to other airless sprayers. Graco is a well-known brand for airless sprayers, and their products are easily available at Home Depot.
If you only need a paint sprayer for a one-time job, renting one from a hardware store like Home Depot can be a cost-effective option. This way, you won't have to worry about maintenance or storage. Additionally, consider the spraying distance, as airless sprayers typically require a distance of about 12 inches for optimal results.
Finally, for small touch-ups or DIY projects, cup sprayers, a type of handheld airless sprayer, are a good choice. They are compact, less costly, and require minimal setup and cleaning time.

Practice your technique
Before you begin spray painting your interior plastic doors, it's a good idea to practice your technique. Spray painting isn't complicated, but it can take a little while to get the hang of it. Practising on a different surface first will help you achieve better results on your doors.
You can set up some old boxes or a piece of plywood and practice spraying on that. Alternatively, you could try painting a large interior wall or a piece of furniture. Practising will help you get comfortable with your sprayer and learn how to control the spray pattern.
The key to a professional-looking paint job is to apply many light coats rather than one or two thick coats. The lighter you spray, the less likely you are to end up with drips and runs. It's recommended to apply at least three light coats, making sure each coat is completely dry before applying the next one.
When you're ready to start painting, make sure the doors are set up correctly. You can lean them against a wall, but it's important to protect any surfaces behind the door and the surrounding area. You can do this by hanging plastic sheets or setting up some sawhorses and placing the doors across them so that you spray towards the floor.
Additionally, remember to remove all hardware, such as handles, hinges, latches, and levers, before you start spraying. This will help you achieve a neater finish and avoid getting paint on these components. Place each piece of hardware in a small plastic bag to keep them together and avoid losing any parts.

Remove hardware and tape off edges
To prepare for spray painting interior plastic doors, it is important to remove the hardware and tape off the edges. This will ensure that only the desired surfaces are painted and that the paint job is neat and professional-looking.
Start by removing any door handles or knobs, as well as any other hardware, such as locks or escutcheon plates. This will make it easier to handle the door during the painting process and prevent accidental paint splatters on these elements.
Once the hardware is removed, it's time to tape off the edges and any remaining metal parts, such as hinges. Use painter's tape or masking tape to carefully cover these areas. Painter's tape is specifically designed for painting projects and will help create clean lines. Press the tape down firmly, smoothing out any bubbles or creases with your fingers, ensuring the tape is as close to the door as possible. This will help achieve a crisp, straight edge between the painted and unpainted surfaces.
When taping off the hinges, you can use an Exacto knife or a putty knife to cut the tape along the edge of the hinge, making it easier to remove the excess tape. This technique will allow you to paint right up to the edge of the hinge, creating a clean, finished look.
Additionally, if your door is made of lightweight plastic, taping down all the edges is crucial. The draft from the paint sprayer can cause lightweight plastic to float, potentially ruining your paint job. Applying tape to the edges will help weigh down the plastic and keep it in place during painting.

Apply multiple light coats
To achieve a professional finish when spray painting interior plastic doors, it is recommended to apply multiple light coats of paint rather than one or two thick and heavy coats. This technique will ensure a neater result with no brush strokes, drips, or runs. It is important to allow each coat of paint to dry completely before applying the next coat.
When applying the light coats, it is crucial to maintain a consistent velocity and continuous motion. This can be achieved through practice on a scrap piece of wood or plywood before painting the doors. It is also important to clean the sprayer nozzle periodically to avoid clogging, which can cause spotting and an uneven finish.
To apply the light coats effectively, it is recommended to use a paint sprayer that is lightweight and easy to handle. This will allow for better control of the spray pattern and help achieve the desired finish. The Wagner Flexio 590 is a popular choice for a paint sprayer, known for its ease of use and smooth finish.
Additionally, when spraying plastic doors, it is important to tape down all the edges of the plastic to prevent them from floating due to the draft created by the paint sprayer. This will ensure a neat and precise paint job. Proper ventilation and the use of appropriate protective gear, such as masks and eye protection, are also essential when spray painting.
By following these instructions and applying multiple light coats, you can achieve a high-quality and professional finish on your interior plastic doors.
